A rare Abernethy Ib malformation was initially misdiagnosed as chronic portal vein thrombosis in a 27-year-old female

Radiology Case Reports, 2022
Abernethy malformation or congenital portosystemic shunt is a rare congenital vascular malformation and anomaly of the splanchnic venous system defined by diverting portal blood away from the liver.

Long-Term Outcomes of Extrahepatic Portal Vein Obstruction-A Nationwide Registry-Based Follow-Up Study From 1987 to 2023. [PDF]

Liver Int
ABSTRACT Background and Aims Extrahepatic portal vein obstruction (EHPVO) is among the main causes of childhood portal hypertension. We analysed nationwide long‐term outcomes of EHPVO in relation to various management options. Methods In total, 62 consecutive patients with EHPVO diagnosed between 1987 and 2023 were followed up through hospital records ...

Shunt-capacitor-assisted synchronization of oscillations in intrinsic Josephson junctions stack

, 2010
We show that shunt capacitor stabilizes synchronized oscillations in intrinsic Josephson junction stacks biased by DC current. This synchronization mechanism has an effect similar to the previously discussed radiative coupling between junctions, however,

Clinical outcome of cerebrospinal fluid shunts in patients with leptomeningeal carcinomatosis

World Journal of Surgical Oncology, 2019
Background Leptomeningeal carcinomatosis (LMC) is frequently associated with hydrocephalus, which quickly devastates the performance of the patient. Cerebrospinal fluid (CSF) shunt is a widely accepted treatment of choice, but the clinical outcomes in ...

Zwitterionic Self‐Assembled Monolayer for Simultaneous Noise Suppression and Hole Extraction in High‐Performance Near‐Infrared Organic Photodetectors

Advanced Functional Materials, EarlyView.
This study presents a new hole transporting material (HTM) mechanism for self‐assembled monolayers in near‐infrared organic photodetectors. The formation of zwitterions induces a strong electric field that significantly increases the work function of HTM‐coated indium tin oxide substrates. The devices exhibit low dark current and noise, along with high

The role of perfusion and diffusion MRI in the assessment of patients affected by probable idiopathic normal pressure hydrocephalus. A cohort-prospective preliminary study

Fluids and Barriers of the CNS, 2017
Background Invasive tests measuring resistance to cerebral spinal fluid (CSF) outflow and the effect of temporary drainage of CSF are used to select candidates affected by idiopathic normal pressure hydrocephalus (iNPH) for shunt surgery.

Fully-Integrated Solid Shunt Planar Transformer for LLC Resonant Converters

IEEE Open Journal of Power Electronics, 2022
A new topology for achieving high leakage inductance in inserted-shunt integrated magnetic planar transformers is proposed. In the proposed topology, two one-segment shunts are placed across the planar E-core air gap and between the primary and secondary
